Due date off by 9 days!!!!

[MamaNae]

So I had my first ultrasound yesterday and the tech measured the embryo at 6w2d.  Mind you, from my LMP, I would have been 7w4d yesterday.  A difference of 9 days!!  This is absolutely crazy because hubby and I were not even doin the dirty when the u/s dates indicate we would have conceived AND, his sperm would have had to survive in me for 8 DAYS before that estimated ovulation date.  I'm not sure what to think about this.  I was keeping track of cervical position and also kept track of days we bd.

The interesting part is that with my son I also was given 2 due dates that were 9 days apart!!  The first one was based on an u/s at about 9 weeks and the second one was from an ultrasound about a month later.   I just wish I knew which date to go by........on a more positive note, the little peanuts heart rate was 121!!

Thanks for reading my rant :)

thats great!!! so weird though...i went last week measured 6 wks 2 days; supposed to be 7 weeks 2 days and our heartbeat was also 121!!! I wouldnt worry too much about the due date thing...i have heard of others who eventually "caught" up during week 12 or so...My first child was due Jan 9th and he showed up Dec 12th...normal as could be....so? Well Good luck to you...

Hey nickie, thanks for responding.  I was thinking the exact same thing earlier.....about being slow growing in the beginning and then catching up a few weeks later.  At least that is the only explanation that makes sense to me since I had the same issue with my son.  The 2nd due date they gave me for him, which was by my lmp, not u/s, is the actual day he was born.  I will wait and see what they measure baby at at my next u/s appt when I will be 13 weeks by lmp.  Will be curious to know if I will be sticking with the dd of 12/30 (lmp) or 1/8/11 (u/s)  :)

Hey I have had this problem also and my doctor referred to my babies as being slow growers. This just means that somewhere along the lines the baby hits a growth spurt after aging kind of slow in the beginning. Both of my other children have been given 2 different due dates and they are still not sure about the correct date to my little girl due in Sept/Oct and both of my other children were born large in weight at 2-3.5 weeks early. I know everyone says that early ultrasounds are more correct but for some of us ladies they are a little off. It sounds like your babies are like mine and they will catch up in size later on. Congrats on the pregnancy!
